Thanks for the contest extension!
I give you the CGU Scimitar.CGU ScimitarCGU Scimitar (Underside)
Surprisingly, the Scimitar weighs only 108g. I double checked my scale because I couldn't believe it at first.
Technically this would mean the $7.99 category. However, I used a lot of big (technic) pieces, so probably a set like this
would cost more. I'll let the judges decide on the category...
A straightforward upside-down and technic connections build, I don't think I used any illegal techniques. Very
limited SNOT work in the back of the center section. The main gun would probably not survive a 7-year-old, but the
rest is quite solid. Not many play features, though I do have four of those ever-popular flick missiles.
